To all whom it may concern:

Be it known that I, JOHN S. HANsnN, a citizen of the United States, residing at Medford, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain Improvements in Machines for Ironing Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings in dicating like parts-in the several figures.

This invention relates to machines for use in finishing boots and shoes, and particularly to machines for treating the uppers of boots and shoes. The upper of a boot or shoe gets more or less marred, wrinkled, and out of shape by reason of the frequent handling incidental to the several operations of making the shoe, and this is particularly so if the shoe is oh the last during a considerable portion oi. the making operations. It is, therefore, the practice in finishing shoes to apply each shoe to an expansible tree which distends theshoe substantially to the shape of the last upon which it was made, and while the shoe is on the tree the upper is treated for etfacing any wrinkles, marks,

. customary to speak of machines in which the tools are not heated as treeing machines and to refer to machines in which the tools are heated as ironing machines The present invention is herein shown as embodied in an ironing machine,'although many features of the invention are applicable also to treeing machines.

The devices for treating the shoe are hereinreferred to as ironing devices or tools, the term tool being used in theclaims to include heated devices adapted for use in ironing shoes as well as unheated devices used for treeing shoes.

A very important feature of the invention consists in improved mechanism for supporting and operating the tools employed for engaging shoes, said mechanism as herein shown comprising means for moving the tools toward and from operative position, andother means for moving the tools over a shoe while in operative position, the expressions operative position and inoperative position being used herein to designate operative and inoperative positions with reference to a shoe to be treated. Preferably the tools for treating one side of the shoe are mounted upon one support and the tools fortreating the other side of the shoe are mounted upon another support, while actuating means is arranged for moving the two supports simultaneously for carrying the tools mounted upon them toward and from operative position. The movement of the tools toward and from operative position is preferably effected by moving the tools laterally with relation to the shoe, and as herein shown the supports are arranged to turn for swinging the tools laterally toward and from position to engage the shoe. If desired, the tools on one side only of the shoe may move toward or from operative position to permit the shoe to be placed in position to be treated and thereafter removed. The mechanism for moving the tools over the shoe is preferably arranged for reciprocating the supports together longitudinally of the shoe. As herein shown the sets of tools carried by each sup port are arranged in two groups, the upper group being adapted for treating the forepart of the shoe upper as the tools are reciprocated in operative relation to the shoe and the lower group for treating the rearpart, including the leg, of the shoe upper. The tools, of which there are a plurality in each group, are so shaped and disposed that together thew, may cover substantially the entire upper of a shoe.

In order to enable the tools completely to treat the entire upper as they are moved over it said tools require to have other movements in the direction of the height of the shoe in addition to their rcciprocations in the direction of the length of the shoe. To indicate the movement in the direction of the length of the shoe I have described the tools in the specification and claims as being moved longitudinally of the shoe and I have referred to the movement in the direction of the height of the shoe by the expression transversely of the shoe. It

is particularly important for those tools which engage the upper adjacent to the rand crease or angle between the sole and vamp to have this transverse movement because styles of shoes the surface of this portion of the shoe varies with and conforms approximately to the spring of the shoe bottom so that for the best results the tools acting on this portion of the upper should be moved transversely of the shoe as they reciprocate over the shoe.

Vith these ends in view an important feature of the invention consists in providing improved'means for moving the tools transversely of the shoe, or toward and from its sole, at the same time that they are reciprocated longitudinally of the shoe. As herein shown the tools of the upper and lower groups acting on each side of the shoe are mounted upon carriers which are movably sustained by the reciprocatingsupports and are caused to move on. the supports transversely of the shoe as they are reciprocated. The movement of the tools transversely of the shoe is herein'shown as effected by cam guides which are arranged to move the oups of tools in and out for causing them to follow paths approximately parallel to the rand crease of the forepart and the rearpart-of. the shoe. Preferably the tool carriers are mounted on their supports for both rocking and sliding movements transversely of the shoe, and preferably also the cam guides by which these movements are effected are arranged for adjustment to vary as desired the extent of the movements of the carriers and tools according to the amount of spring of different styles of shoes. As herein shown, the tools are yieldingly connected to their carriers whereby they may adapt themselves to the contour of the surface of the shoe engaged by them, and preferably also the tools are arranged to have a limited amount of free rocking movement sidewise to facilitate their adaptation to the surfaces being treated. I have herein shown the tools as rollers adapted to treat. the upper by rolling pressure, and while I prefer to use rolling tools for ironing shoes, it is within my invention to use any usual or suitable form of tool according to the class of work to be treated.

A further feature of the invention consists in novel means for supporting the shoes and presenting them to the tools by which memo? they are treated. As herein shown a plurality of expansible trees for supporting the shoes are carried by a turret which is adapted to be rotated for presenting each tree first to means for expanding the tree, then in position for the shoe to be treated by the ironing or other tools, and later to a device for releasing the locking means which has held the tree expanded, thus enabling the tree to collapse for facilitating the removal of the treated shoe and the-application of another shoe.

Another feature of the invention consists in providing automatic mechanismfor ac tuating the tree-expanding means whereby the'workman is relieved of t e labor.here tofore necessary in expanding'the trees to distend the shoes. This automatic mecha-- nism is herein shown as comprising means adapted to be positioned at the will of the workman for rendering said mechanism operative.

Still another feature of the invention relates to automatic means for actuating the turret to move the trees toward and from operative positions with relation to the several means for acting on the trees and on the shoes carried by the trees.- As herein shown the machine is providedwith means for holding the turret from rotation'where- W by the trees may be retained in operative relations to the cooperating means, and connections are herein shown between a driven member of the machine and said retaining means whereby the turret is released to per- N0 mit it to be turned. Connections are also herein shown between a driven member of the machine and the means for moving the ironing devices into operative position whereby when the turret has been rotated m5 to present a shoe in position to be treated the ironing devices are automatically moved into operative position.

The construction and arrangement of the several parts of these portions of the in- 11 vention constitute features of the invention which, together with other features, including certain details of the machine and combinations of parts thereof, will be set forth in the following description and pointed 5 'by the dotted line 4-4 in said figure. Fig.

Figs. 13, 14, and 15 are detail views of the mechanism for turning the turret to present the trees successively in position for the shoes carried by them to be operated upon.

a Fig. 16 is a detail view of means for holding a tree against rotary movement in the turret. Fig. 17 is a perspective view of the means employed for holding the leg portion of the shoe taut about the leg portion of the tree. Fig. 18 is a detail view showing means for rendering certain of the ironing devices inoperative.

The machine herein shown as embodying the invention has a main column 2 and a leg 4 which sustain a framework (5 and a table 7, the frame being provided with bearings for a driving shaft 8 upon which are mounted fast and loose pulleys. The driving shaft is connected by speed-reducing gears 10, 12, 14, and 16 with a toothed disk 18 secured to a short shaft 20 mounted in a bearing in the frame and provided on its inner end with a crank disk 22 from which depends a link 24 connected to a lever 25 which is pivoted at 26 to a lug on the column 2. The lever 25 is continuously vibrated by its connection with the crank disk in a. vertical path for purposes which will later appear.

The column 2 is provided with bearings for a vertical shaft 30, see Fig. 3, upon which is secured a turret 32 having a plurality of radial socket members 34- to receive the shanks of the expansibletrees which are employed for distcnding the shoes and for supporting the shoes while the ironing operation is being performed. The trees may be of any usual or suitable construction and those shown are of the well known type which are adapted to be expanded and contracted by means controlled by a longitudinally movable member, which is drawn out for expanding the tree and reversely moved by a spring for effecting the contraction of the tree. The said longitudinally movable member, which is indicated at 35 in Fig. 5, is connected by a pin 38 to the head of a guide rod 39. The turret may be turned to present the trees one at a time to an actuator 40, shown as a lever adapted to engage the head of the guide rod 39 for drawing outwardly the movable member 35 of the tree which is in position to be expanded.

The actuator 40 is shown as fulcrumed on the column 2 and is provided with means by which it may be operatively connected at times to a continuously oscillated operating lever and then automaticall disconnected therefrom after the lever lias made one stroke. To this end the actuator is herein shown as forked at its lower end to receive a plate 42, which is pivoted to the actuator at 44, the heavier end of the plate being at the back of the actuator, or the left hand side thereof, as seen in Fig. 5, so that said rear end of the plate will swing downwardly by gravity until the tail-piece 48 rests upon the head 4.) of the operating lever 50 and the rear end of the plate is in the path of said head-piece 4!). In this position of the parts the plate 42 connects the ac tuator to the operating lever for causing the former to be moved for expanding the tree. As it is desirable to expand a tree only at intervals and not at every oscillation of the lever, means is provided for holding the connecting plate 42 normally out of operative relation to the operating lever, and this means as herein shown comprises a plate 41 pivoted at its rear end to the actuator at 43 and adapted to rest by gravity upon an adjustable stop screw 46 upstanding from the plate 49.. The weight of the plate 41 upon the stop screw holds the connecting plate 42 normally in the position shown in full lines in Fig. 5 with its stud against the plate 41 and the rear end of the connecting plate out of the path-of the operating lever. The plate 41 is provided with a handle 47 by which it may be manually lifted to allow the connecting plate to assume the dotted line position when it is desired to have the actuator moved for expanding a tree. Cooperating hooks 51 and 53 carried respectively by the plate 41 and the table 7 are arranged to hold the plate 41 in its raised position, until, during the oscillation of the lever and actuator, the plate has been moved to the right in Fig. 5 far enough to disengage the hooks automatically and on the return movement of the actuator the parts will resume the full-line position shown in Fig. 5. By means of this arrangement the actuator 40 may be connected with the lever at the will of the workman and will remain in operative connection therewith until it has been actuated, whereupon it ill be automatically disconnected from said lever at the end of one oscillation of the lever. The lever 50 is represented as a bellcrank lever having a vertical and a horizontal arm and fulcrumed at 52 on lugs extending from the column 2. The horizontal armextends over the continuously vibrated lever 25 before described and is arranged to be rocked constantly by that lever. To this end the lever 25 and the horizontal arm are provided with a contact plate and an adjustable contact screw 54, the screw en abling the relative positions of the levers 25 and 50 to be adjusted and thereby the extent of movement imparted to the longitudinally movable members of the trees to be varied. It-is found in practice to be desirable to introduce a yielding element into the mechanism by which the longitudinally movable members are ing the trees, and as herein shown, this is provided by movably connecting the headpiece 49 to the lever 50. The head-piece is formed on the upper end of an arm which is pivoted to the lever 50 at 56 and extends downwardly below the fulcrum of lever 50 where it is engaged by one end; of a spring '58, the other end of which is connected to the continuously vibrating lever 25 as shown in Fig. 1, or it may be connected to the horizontal arm of the 5. The spring 58 permits the head-piece to yield in the event of excessive resistance to the expansion of a, tree for distending a shoe preparatory finishing operations.

It is desirable to provide means for holding the leg portion of the shoe taut about the leg portion of the tree While'the shoe is being treated, and for this purpose I have 1'irovided means adapted to be connected to the front corners of the upper, as, for example, by means of the top lacing hooks or eyelrts, for holding the upper under tension upwardly and forwardly. As herein shown, this means comprists a rod 61 longitudinally adjustable in aclamp 63 carried by the tree leg. o the front end of the rod are pivotally connected levers 65 carrying hook members (37. Springs 69 are connected at one end to the rod 61 and at the other end to the arms 65. The arrangement is such that the arms fiii'extend at an angle to the rod 61 and the springs tend to turn the arms about their pivotal connection with the rod. -This results in producing a tension upon the leg portion of the upper, pulling it upwardly and forwardly and thereby holding it taut both in the direction of the height of the shoe and in the direction of its length.

The device for holding the leg portion of the shoe in position upon the tree is not claimed herein, since it is claimed in a divisional application. Serial No. 310,759, filed April 9, 1906, which has matured into Pat-- ent No. 850,881, granted April 16, 1907.

In the machine herein shown as embodying the invention the means described for actuated for expand-- lever 50, as shown in Fig.

to its being treated in the mentor expanding the trees is located at one side of the mechanism forironing the shoes so that a shoe may be applied to and distended by one tree while a shoe on a previously expanded tree is being treated by the ironing mechanism, and the rotatable turret enables the trees to be moved from operative relation to the expanding means into operative relation to the ironing mechanism. It is desirable for the best results that each shoe remain on the expanded tree for as long a time as is convenient in order that the shoe may better retain the shape of the-tree. I have, therefore provided means for locking each tree in expanded condition and holding the tree expanded while it is being moved and being treated by the ironing mechanism, and preferably until the shoe is to be removed and another shoe applied to the tree. To this end the head of the guide rod 39 is provided with a lateral lug G2, and a latch (31, see Figs. 5 and 6, is pivotally mounted on the turret 32 adjacent to each tree socket and is yieldingly held by a spring 66 in position to engage the lug 6-2 when the guide rod and the longitudinally movable member of the tree have been forced by the actuator L0 into position to expand the tree. The latch (Slis provided with a depending handle or operating member 68 by which it may be moved either manually or by engagei'nent with a suitable stop for unlocking the tree and permitting it to be contracted. The spring 66 is shown as connected at one end to said member (58, while at its other end it is fixed to the turret 32.

For automatically unlocking the trees I have provided means shown in Fig. 2 arranged to act upon each tree while it is being moved into operative position with relation to the actuator -10. The means shown for this purpose comprises a stop 70 mounted on the head 72 of a post 74 see Fig. 1, and having a beveled stop face 75. The stop face 75 is located in position'to engage the operating member 68 when a tree is moved toward the right in Fig. 2 past the stop, and to force said member in the direction for withdrawing the latch 64 from looking engagement with lug 62 on the head of guide rod 39. Preferably the stop 70 is pivotally mounted so that it may swing out of the path of the operating member 68 without withdrawing the latch 64; if a tree is moved toward the left, as may occasionally be desired in the use of the machine. The stop is acted upon by a spring 76, which holds it normally in operative position against a pin 78 on the post head 72. The operating members or handles are so positioned and are of such form that they may conveniently be grasped by the workman at any time to unlock a tree and permit it to collapse.

The turret carrying the trees may be turned either manuall or by mechanism connected with the driving shaft. In the main figures of the drawings I have shown the turret as adapted to be turned by the operator, while in Figs. 13, 141, and 15 of the drawings I havedisclosed one form of mechanism connected with the driving shaft for turning the turret. This mechanism includes a ratchet-faced disk 80 Secured to the shaft 30 and provided with teeth equal in number to the trees supported by the turret. A pawl.82 adapted to engage the ratchet disk is mounted on a horizontally movable pawl carrier 81 connected to an arm 86, which is pivoted on a rod 88 supported in the frame 6 and is arranged to be actuated by a cam 89 on a cam shaft 90. The cam shaft is mounted in bearings in the frame 6 and supports a sleeve shaft 92, which, in the modification referred to, carries "a gear 94 continuously driven by a pinion 19, see Fig. 13, secured to the shaft which carries the gear 18. The sleeve shaft or the face of the gear 94 is provided with one member of a clutch the other member of which is splined on the cam shaft 90 and is adapted to be moved into engagement with the continuously driven member by a manually controlled lever 96 and to be moved automatically out of engagement with said continuously driven member by an inclined lug 97 formed on the face of the gear 9 1 in position to engage a contact screw 98 carried by 'the lever 96. This arrangement enables the cam shaft 90 to be connected to the-driven member at the will of the workman and given one rotation, after which it is automatically disconnected from the driven member and comes to rest. The pawl carrier 81 is shown as made intwo sections yieldingly held together by a spring 99 through which the rotation of the turret is yieldingly effected. b

Retaining means is provided for holding the turret stationary with one tree in operative relation to the actuator which expands it and another tree in operative relation to the tools for treating the shoe. The retaining means is herein shown as arranged to cooperate directly with that tree which is in position for the shoe carried by it to be treated, although it might obviously be located to act directly upon any other one of the trees or with any portion of the turret. The preferred embodiment of retaining means (see Figs. 1, 2, and 3) comprises an upright lever 100, which is fulcrumed at 102 and the upper arm of which extends through a guide 10% which braces the lever laterally, or against movement in the direction oftravel of the trees. The lever is engaged at its lower end by a spring 106 which is connected to the frame and holds the upper end of the lever yieldingly pressed outwardly. Each tree has rigidly secured to its under side ablock 108 in osition to cooperate with the upper end 0 the lever 100 when the tree is in o erative position with relation to the tools or treating the upper of the shoe carried thereon. As shown in the sectional view Fi 7, the block 108 is provided with incline faces 107 to engage the lever and force it backwardly against the tension of spring 106 as the block and tree are swung toward the lever. The tree and block are normally moved in the direc tion of the arrow in Fig. 7, and the shoulder 109 formed by the rear side of the notch in the block is higher than the shoulder on the other side of the notch and constitutes a stop or abutment for arrestin the movement of the turret and stopping it in desired position with one tree in its operative relation to the tools and another tree in its operative relation to the actuator 10. The retaining lever "is caused by its spring 106 to seat itself in the notch of the block as soon as the trees come into their operative positions and the lever then holds the entire turret 32 from swinging movement in either direction until the lever is withdrawn. The retaining lever may be with drawn manually to permit the movement of the turret, or it may be automatically actuated away from the block 108. For manually withdrawing the retaining lever a hand lever 110 (see Figs. 1 and 2) is'fulcrumed on the frame at 111, the short arm of the hand lever being in position to engage the lower portion of the retaining lever while the long arm forms a handle located in con venient position to be grasped by the workman.

When the mechanism heretofore described for turning the turret is employed I prefer to use also mechanically operated means for withdrawing the retaining lever to release the turret preparatory to its being turned. As herein shown a second arm 112 is pivoted on the rod 88 and arranged to be actuated by a cam 114 on the shaft 90. The arm 112 carries a hook arranged to engage a stud 118 projecting laterally from the lower end of the lever 100. This mechanism for withdrawing the retaining lever and the mechanism for turning the turret are preferably used together, but it will be obvious that either of these mechanisms may be used without the other if desired.

In the embodiment of the invention herein shown the mechanism for treating the shoes upon the expanded trees includes two vertically reciprocating supports, shown as shafts 150 guided and adapted to have a limited amount of turning movement in bearings 152 in the end of the frame oppo site to that at which the turret is located. The shafts extend at their lower ends freely through a cross head 154 and are provided with collars 156 by which they are held to the cross head to be reciproeated thereby. The cross head is connected by a'link 157 to the continuously vibrating lever 25, by means of which the shafts and the mechanism carried thereby areconstantly moved up and down. The shafts 150 are guided near their upper ends in a bracket 158, which is sustained by a post 160 seated in a platform 9, which connects the upper edges of the side portions of the frame 6 at this end of the machine. The shafts 150 support the tools for treating the shoe, these tools being herein shown as devices adapted to be heated for performing the operation of ironing the shoe, and are, therefore, sometimes referred to herein as ironing devices, although it will be understood that the invention is not dependent in any way upon the particular means employed for treating the shoe to finish it or upon the fact that the tools are heated. A. separate set of ironing devices is carried by each shaft- 150 and these sets of devices are arranged for treating simultaneously the opposite sides of a shoe located between them; The shafts and the ironing devices move up and downcontinuously, in the construction herein shown, and the shafts are adapted to be turned iiiopposite directions through a portion of. a revolution, shown as approximately 90. Turning movement of the shafts in one direction swings the two sets of ironing devices from a position adjacent to each other for operating upon a shoe located between them to a position which will permit the tree bearing the shoe which has been treated to be swung by the rotation of the turret away from position to be operated upon and a tree bearing another shoe to be brought into position to be operated upon. To this end each shaft is provided with a segment block or gear 162 connected to the shaft and formed integral with or secured to the lower end of a casting 248 fastened to the shaft and which extends parallel with the shaft and is provided at its er end below the bracket 158 with a WP guide 249 for the shaft. Between the two segment blocks and in operative engagement with bothof them is a rack bar 164 which is attached by a bolt 166 to a longitudinally movable rod 170 guided in bearings on the under side of the platform 9. The rod 170 and the rack bar 164 are normally held by a spring 172 in the position shown in Figs. 1 and 2, in which position the shafts 150 have been turned to move the sets of ironing devices away from each other to permit the turret to be swung, this position'of the sets of ironing devices being hereinafter referred to as their inoperative position. The rod 170 and the rack bar 164 are reversely moved for turning the shafts to" put the ironing devices into the position shown in Figs. 3 and 10, this position being herein referred oarse? to as'their operative position, by a cam-actuated arm 174, see Figs. 1, 2, 3, and 15. The arm 174 is pivoted on the rod 88 before mentioned and is held by a spring 176 against an actuating cam 175 on the cam shaft 90. The upper end of thearm 174 is provided with a roll which is located in alinement with the rod 170 and in the rotation of the cam 175 may force the rod to the right in Figs. 1 and 2, whereby the shafts 150 areturned for swinging the ironing devices intc their operative positions.

If the mechanisms heretofore described for. releasing and turning the turret are employed the cam 175 will be so positioned on the shaft 90 with relation to the cams .89

and 114 that the ironing devices will be swung into their operative positions after the turret has been turned. If the said mechanisms are not employed'then preferably the cam shaft will run constantly and the arm 174 will be continuously vibrated. For the purpose of causing the rod 170 to be actuated only at the desired times said rod will then be provided with a movable block 177 pivotally connected to the rear portion of the rod and normally held out of alinement with the rod 170 and arm 174-, but adapted to be moved at the will of the operator into alinement with these parts for causing the rod to be actuated for swinging the ironing devices into operative position. For moving the block 177 into alinement with the rod 170 and arm 174 an arm 179 is pivoted at 181 to the rod 170 and is connected through a spring 183 with the block 177. The rear end of the arm 179 has a pin and slot connection with a hand lever 185 pivoted at 187 to the table of the machine. The hand lever and the parts with which it is connected are normally held by aspring 189 in the position shown in Fig. 2, but may be moved in opposition to said spring for swinging the arm and the block to the left in Fig. 2 to cause the block to occupy an operative position in alinement with the rod 170 and arm 174. It is desirable to employ means for retaining the block temporarily in its operative position, and to this end I have provided a plate 191 over which the rear portion of the arm 179 is adapted to be moved by the lever 185. On the plate 191 is arranged a stop 193 having an inclined wardly by the arm 174. In such advance movement the arm 179 is carried forwardly beyond the stop 193, after which the spring 189 may move the parts into their normal positions shown in said Fig. 2. A'stop 195 Loeneov limits the movement of the parts in the dircction in which they are impelled by said SPIIHO.

The rod .170 and rack'bar ltiat are automatically secured in the position to which they are moved by a locl zi ng device comprising a latch .180 pivoted at 182 (see Figs. 2 and 12) to the end of the rack bar nearest the turret. The latch is adapted to cooperate with a stop 18d secured to the platform 9 and is of sullicient weight to cause it to drop by gravity behind the stop when the racltbar has been moved into position for this movement to take place. I prefer to provide the machine with means for automaticallyreleasing the latch 180 rrom the stop'lSel to permit the spring 172 to move the rack bar 164 for swinging the ironing devices away from the shoe after the shoe has been treated during a predetermined number of reciprocations of said ironing devices.

As shown, a shaft 186 is provided with tripping device 188 and has at one end a crank arm 190 which adapted to he so gaged actuated for lifting the latch by an arm of a ratchet wheel 19st. The ratchet w "l is acted upon by suitable means, stu vn as a weight, for holding the arm 192 normally against a stop pin 19?. The stop pin may be positioned in any one 01" a series i holes in the side of the frame t3 accordio to the number of reciprccations which it desired to allow the ironing devices to make while in operative relation to the shoe being treated. The ratchet wheel is operated for moving the arm 192, from a predetermined initial position against the stop 19? into position for operating the latch, by means of a pawl 196 carried by one of the vertically reciprocating shafts 150, the pawl being arranged to turn the ratchet the length of one tooth for each rcciprocation of the ironing devices. A locking pawl 198 is arrangedtto engage ratchet teeth form d on the side of the ratchet wheel and is carried by an arm 199 through which the shaft 1.50 moves in its reciprocations but which is arranged to be turned by said shaft to carry the owl 198 out of engagement with the ratchet wheel when the ironing devices are turned out of operative relation to the shoe. The pawl 196 also is moved out of operative relation to the ratchet wheel when the shaft isthus turned. it will now be understood that the stop pin 197 will be positioned to expose to the action of the pawl 196 a number of ratchet teeth equal to the number of reciprocations it is desired to have the ironing devices make while in contact with the shoe. 'lhereatterwhenever the rack bar 164 is actuated to turn the shaftslt) t'or swinging the ironing devices into operative position the pawl 196 and the locking pawl 198 will be brought into operative positions with relation to their respective sets of teeth on the ratchet wheel, and then during the reciprocations of the ironing devices the ratchet wheel will be turned step by step for moving the arm 192- toward the crank arm 190. During the last step of this movement of the ratchet Wheel the arm 192 will engage the arm 7.90 and turn the shaft 186 for lifting the latch 180. As soon as the latch is lifted the spring 1'32 will move the rack bar in the direction for swinging the ironing devices into their inoperative positions, and then the turret may be turned for moving the tlflltltul shoe away and bringing another shoe into position to be treated. In the movement of the ironing devices toward inoperative position the pawl 196 and the locking pawl 198 are also moved out of operative relation to the ratchet wheel and the wheel is then moved backwardly by the weight referred to until its arm 192 engages the stop 19?. ihc shaft 186 is provided with a handle ll'ifl by means of which it may be manually turned for lifting the latch 180 and permitting the ironing devices to be swung from their operative position to their inoperative position at any time during'thc operation of the machine. If desired, the automatic means for releasing the latch to permit the ironing devices to move to inoperative position may be omitted and the operator will then release the latch at will by turning the handle 161.

The sets of ironing devices supponed by the two shafts 150 and which act upon the opposite sides of the shoes are herein shown as duplicates of each other, except in a minor particular hereinafter referred to, and the several parts of these devices upon the two sides of the machine will be indicated by the same reference characters. Each shaft 150 supports two carriers 200 and 5202 which are rigidly secured to the shafts to reciprocate and rotate with them. The carriers sustain lower and upper groups of ironing devices, the upper group of devices being arranged to act upon the forepart of a shoe and the lower group of ironing devices being arranged to act upon the real-part, including the leg portion, of the shoe. The carrier i200 con'r prises a laterally projecting forked arm 204 which receives a rectangular slide block 206 (see Figs. 4 and 10), said slide block supporting a fulcrum pin 208 upon which is mounted a carriage lever 210. The carriage lever is formed with upwardly projecting arms 212 and 214 located at its opposite ends. From the arm 212 projects laterally a pivot rod 216 upon which are mounted the several holders 218 of the lower group of ironing devices 220. In the illustrated embodiment of the invention this group comprises :tour ironing devices, shown us rollers mounted to turn freely upon axles carried by stems 222; The stems 222 are shown as extending through lugs 224: on the holders and as provided between the lugs 224 with collars 226. Provision is made for permitting .the stems to have alimited amount of rotary movement in the lugs in order to enable the -ironing devices to position themselves .according to the contour of the portion of the shoe engaged by them. To this end the collars 226are rigidly secured to the stems and are provided with notches adapted to receive a relatively narrow stop on the holder. This construction is illustrated best in Figs. 9 and 11 and may be substantially the same for each holder. A spring 227 is employed in connection with certain of the ironing devices to hold them normally at one limit of their movement about the axis of their stems, said spring connecting the collar 226 with the holder, as shown in Figs. 9 and 11. The holders 218 are adapted to turn about the pivot bar 216, their movement in one direction being limited by stop screws 230 which are mounted in lugs'232 projecting laterally from the heads of the holders. The stop screws are adapted to engage the upper face of a bar 234: secured to the upper arm 212 of the carriage lever, the outer ends of the bar and the pivot rod being connected by a plate 235. Springs 236 are connected to the lugs 232 and to a fixed part, shown in Fig. 11 as a. downward extension of the bar23al, and'normally hold the stop screws against the bar 23 When the ironing devices occupy their operative position and are reciprocated in contact with. the shoe the springs 236 hold the devices yieldingly against the shoe, but permit them to move relatively in accordance with the contour of the different portions of the shoe. The normal relative positions of the ironing devices of the group may be varied by adjusting the stop screws for causing the devices to upon the shoe to the best advantage.

if it is undesirable to treat any portion of the shoe, as, for example, the upper portion or quarter, or the shoe to be treated is alow or Oxford shoe, provision is made for rendering one or more of the ironing devices inoperative. To this end a plate 237 may be mounted on the upper face of the bar as shown in Fig. 18, said plate being provided with recesses in which normally the stop screws 230 are seated. The recesses increase in width from the. right-hand end of the plate, viewing Fig. 18, toward the left-hand end and are provided on their rear or left-hand sides with inclined walls 239. An adjusting screw 241 is mounted in the. end of the bar 23% and is provided with collars which permit it to rotate, but hold it against longitudinal movement in the downturned end of the plate. By manipulating the adjusting screw the plate may be moved to the right from the position incense? shown in Fig. 18 to bring the inclined walls I of the recesses into engagement with one stop screw after another and thereby raise the stop screws successively out of their recesses. By difi'erently adjusting the plate 237 it may be made to support one or more, or even all of'the ironing devices of a group oftools out of operative engagement with the shoe. For ironing low cut shoes it will usually be found desirable to adjust the plates 237 of both lower groups of tools to render inoperative all the tools of each lower group except the one which runs next to the rand crease.

The arm 214 of the carriage lever is acted upon by means which preferably slides the lever in the forked arm 204 and also rocks the lever about the pivot 208 transversely of the shoe during the reciprocation of the ironing mechanism. The sliding movement causes the ironing devices as they move over the upper to follow paths approximately parallel to the sole andthe rand crease of the shoe whereby the ironing devices adjacent to the sole may actupon the upper close to the rand crease throughout their reciprocation. The rocking of the carriage lever causes the ironing devices to face at all times in the direction of their advance movement, so that they roll freely over the stock in curved paths instead of rubbing endwise, as they" would do if the carriage lever had a sliding movement only in its carrier. It is to be noted that all of the ironing devices of each group partake of the sliding and rocking movements and therefore the relative lateral positions of the tools remain unchanged so that the up per may always be completely covered without the necessity of one tool overlapping the path of another to a large extent or incurring the risk of a gap being left between the paths of adjacent tools in any portion of their reciprocations. The ironing devices next the rand crease preferably are formed with acting faces shaped substantially as shown to adapt them to work into the rand crease of the shoe. The means for actuating the carriage lever 210 to move the ironing devices transversely of the shoe is herein shown as a fixed cam guide or plate 240 provided with a cam slot 2&2 which receives two studs 24 i projecting laterally TlOI n"tl18 arm 214,01 the car 'iage lover. The cam plate is attached by a bolt 2% to the casting 248 heretofore described asprovided at its lower end with the segment gear 162and at its upper end with the bearing 249, said casting being connected to the shaft 150 by means which permits the shaft to reciprocate relatively thereto but causes the casting and the parts carried. by it to turn with the shaft. The upper end of the cam plate i's'slotted and is adjustably secured in position by means oi": a. clamping llilti LOBLOE)? bolt 256. The plate may be adjusted about its pivotal connection at 246 according to the spring or longitudinal curvature of the bottom of the shoe being operated upon, thereby to cause the ironing devices to slide and rock with relation to the carrier more or less for acting properly upon shoes differing in shape. The carrier 200 is rovided with an arm 260 (see Figs. 2 and 3 which extends into a guideway 262 formed in the casting 248 and insures that the carrier and thecasting with its attached cam plates shall move together when the shaft 150 is turned.

The carrier 202 is secured to the shaft 150 above the carrier 200 and is provided with a similar forked arm 304 in which is guided a rectangular block 306, which supports the fulcrum pin 308 for the carriage lever 310 on which is mounted the upper group of ironing devices. The carriage lever 310 has vertically extending arms 312 and 314. The arm 312 supports a laterally projecting pivot rod 316 upon which is mounted the holder 318 for the ironing device 320 which is adapted to act upon the upper of the forepart of the shoe adjacent to the sole. A bar 322 (see Fig. 3) extends'parallel to the pivot rod 316 and is adapted to be engaged by an adjustable stop screw 324 carried by a laterally projecting lug on the holder 318, said stop screw adjustably limiting the movement of the holder about the pivot rod in one direction. .The holder is acted upon by a spring 326 for yieldinglj' pressing it toward the shoe as far as the stop screw 324 permits. The arm 3120f the carriage lever also supports a second pivot rod 330 upon which is mounted the holder 332 for an ironing device 334 which acts upon the side of the forepart of the 1 i ironed.

shoe above the ironing device 320. The holder 332 is provided with a stop screw 3355 for engaging a bar 340 to limit the move ment of the holder abou its pivot bar in one direction. A spring 342 is connected to the holder for pressing the ironing device 33-t against the work,

As thus far described the groups ofiron ing devices upon the opposite sides of the machine are the same. One of the upper groups of ironing devices, herein shown as the group on the right-hand side of the ma chine viewing Fig. 4, comprises a third iron ing device 350 for acting upon the middle portion of the forepart of the shoe, as ind cated in Fig. 10. The ironing device 350 is carried on a holder 352 (see Fig. 4) mount ed on a pivot rod. 354 and pressed by spring 356 yieldingly toward the work.

The arm 314 of the carriage lever 310 for the upper group of ironing devices isprovided with studs 360 which stand in the slo?v of a'cam guide or plate 362 and cause the: lever to slide in the forked mm 304 and to device 320 is caused to follow a rock about the pivot pin 308 for shifting the ironing devices in the direction of the height of the shoe as said devices are reciprocated vertically, whereby the ironing ath approximately parallel to the edge of t e innersole in order that it may act upon the upper close to the rand crease throughout itstravel. The cam plate 362 is connected at 364 to a plate 250, which is bolted to the casting 248 and spaced from the casting far enough to receive the two cam plates 240 and 362. At its upper end the cam plate is adjustably connected to the plate 250 by a clamping bolt 366 extending through a slot in the cam plate, as shown most clearly in Fig. 10. This provision for adjustment enables the cam plate to be differently positioned for the purpose of adapting the ironing devices to act upon shoes having varying degrees of spring or longitudinal curvature in the forepart. It'is found in practice that it is not often necessary to adjust the cam plate which controls the lower group of ironing devices inasmuch as shoes ditl'er little in the amount of spring in their rear portions. It is, however, quite frequently desirable to adjust the cam plate which controls the upper group of ironing devices because different st les of shoes differ much in the spring of their foreparts. For the purpose of facilitating the adjustment of the upper cam plate 362 I have provided a measuring device by means of which the relative spring of different shoes may be ascertained, the measuring device havinga graduated scale corresponding to a scale on the cam plate. The measuring device is herein shown as a bar 370 adapted to be rested upon supports 372 carried by the plates 250 at about the level occupied by the toe and of a shoe when in position to be '.li1e bar 3'26 is provided with an arm 374 having merited upon it a graduated scale and a similar graduated scale is marked on the upper end-365, of the cam plate 362 in such position that the operator when making the adjustment of the cam plate can readily see the scale. The arrange ment is such that proper adjustment of the cam plate will be attested by bringing adjacent to the edge of the plate 256 anumber on the scale corresponding to that number on the arm 374 which is nearest to th l 0f the toe oi the solo The ironing devices; are shown as heated by iiumes, the has being delivered by tubes 366 "from a suitable source of supply to distriluurrs 382 carried on the upper ends of the shafts 1.50. From thence extend tubes l 384 to the burners 386 located adjacent to the ironing devices of the upper groups. A tube 386 eirtcuds from the distributer 382 to the bar 934-, which is chambered out as shown in saw-lion in Fig. 11 and serves as a distrihm from which extend tubes 388 to llilti ill tree is provi ed on its upper 1 member of applies t the burners 390, which are arranged to direct a flame against the ironing devices of the lower group, Stop cocks are provided by means of which the gas can be shut ofi from any tool which it is not desired to heat,

The shank portions of the trees which are received in the radial socket members 34: of the turret are cylindrical to enable the'trees to he turned for facilitating the application of the shoes to the treesand also any hand operations which it may he desired to perform upon the shoes while they are on the trees. It is desirable to restrict the turning movement of the tree at certain times-as, for instance, when the shoe is being treated by the ironin devices-and to this end each face with a stud. 3J1 adapted to he engaged. by a forked latch 37? pivotally mounted on the socket the turret Ereferahly and as shown, the stud and forked latch fit loosely so as to enable the tree to have a slight turn-- ing'moveinent to permit it to adapt its angular position to the pressure 03% ironing devices. p

in the use of themachine the tree is automatically unlocked by the device 70, to enable it to contract, or it may he unlocked manually by pulling son the downwardly extending einher 68 c the latch ca. When the tree n been contracted the workman ne tree a shoe to he treated, turns the latches 373, into operative eizaagement with. the 371, a secures the nooks 67 to the ir corners c the shoe upper for holding e leg portio of the she taut on the tree.

If the shoe to %e treated is a low cut or Oxford shoe the slides 237 may be adjusted to hold out of operative relation to the shoe those ironing devices of the lower groups which are not required. Also if a portion of the shoe upper, as, for example, the quarters or the quarters and the rear 1; ion of the vamp, consist of ieather or other material which it is undesirable to treat with heated ironing devices the gas fiame may he turned ofi from the devices which act on such portions of the upper, or the slides 23? may be adjusted to hold such devices out of contact with the shoe; is also he understood that any other tools may be substituted for the roll shown, as, for example, rubbing tools which may he heated for ironing the uppers or used without artificial heat for tracing the shoe uppers,
